The principle of cosmetic oil-absorbing paper is mainly based on two physical phenomena: adsorption and infiltration.
First, the adsorption principle is that the surface of the oil-absorbing paper has a certain lipophilicity, which allows the oil to be adsorbed on the paper. Adsorption is a physical phenomenon caused by a substance passing through the surface of an adsorbent. The surface of the adsorbent has a large specific surface area and a certain chemical activity, and can adsorb surrounding substances. The fibers of the oil-absorbing paper are hollow like bamboo, and the shape and surface area of the lumen are different. The larger the surface area, the stronger the ability to adsorb oil. These fibers have hydrophobic and lipophilic properties, which enables the oil-absorbing paper to effectively absorb the oil on the surface of the face.
Second, the infiltration principle is that the oil-absorbing paper usually adopts the bottom surface processing method to make its fiber spacing appropriate, forming a capillary action, so that the paper has infiltration characteristics. The capillary action of the paper allows the oil to be evenly distributed in the fiber spacing of the paper, and diffuse inward through the capillary action of the surrounding paper.
In summary, cosmetic oil-absorbing paper effectively removes excess facial oil by utilizing the physical phenomena of adsorption and infiltration, keeping the skin fresh and clean
